Can't build .dll in visual studio

I'm trying to build a simple .DLL in visual studio but i'm getting the following errors:
IntelliSense: expected a ';'
IntelliSense: cannot open source file "stdafx.h"
error C1083: Cannot open include file: 'stdafx.h':

The .dll is very simple and contains one header and just a cpp, coded as follow:
header:

C++

#ifndef INDLL_H
#define INDLL_H

#ifdef EXPORTING_DLL
extern __declspec(dllexport) int Triple(int);
#else
extern __declspec(dllimport) int Triple(int);
#endif

#endif

.cpp :

C++

#define EXPORTING_DLL

#include <stdafx.h>
#include "Header.h"

void APIENTRY DllMain()
{
	return TRUE;
}

int Triple(int x)
{
	return x * 3;
}

What's wrong here?

Solution 2

The problem is that your #include for stdafx.h indicates that it will be found in the system libraries. You should change it to

C++

#include "stdafx.h"

with double quotes, so the compiler looks for it in the source directory.

Solution 1

Make sure that your project contains file with name stdafx.h if not create another project and copy the file from there. Also try changing #include <stdafx.h> to #include "stdafx.h".

Hope, it helps :)
